The upper end of the PC board assembly 2 is clamped in the special-shaped aluminum pipe extension structure 21. The inner side surface of the lower PP shell 4 is provided with 3 special-shaped aluminum pipe screw positioning columns 42, and the 3 special-shaped aluminum pipe screw positioning columns 42 respectively penetrate through holes corresponding to the special-shaped aluminum pipe extending structure 21 and the PC board assembly 2 and then are fixed by screws 39.

Two PCB board screw positioning columns 43 are arranged on the inner side surface of the lower PP shell 4, and the PCB board screw positioning columns 43 positioned at the upper end of the lower PP shell 4 sequentially penetrate through holes corresponding to the PCB board 8, the rear plug extending structure 38 and the hook shaft 7 and then are fixed by screws 39; the PCB board screw positioning column 43 located at the lower end of the lower PP shell 4 sequentially passes through the corresponding through holes on the PCB board 8, the PC board assembly 2 and the hook shaft 7, and then is fixed by the screw 39.

Two hook shaft screw positioning columns 40 are arranged on the inner side surface of the lower PP shell 4, and the two hook shaft screw positioning columns 40 respectively penetrate through corresponding through holes in the hook shaft 7 and then are fixed by screws 39.

Two sides of the inner side surface of the lower PP shell 4 are respectively provided with a decoration strip screw positioning column 41, and the decoration strip screw positioning column 41 on the left sequentially passes through holes corresponding to the assembled lower decoration strip 12, the PC board assembly 2 and the upper decoration strip 11 and then is fixed by a screw 39; the right trim bolt positioning post 41 passes through the through holes corresponding to the through holes on the PCB 8, the lower trim 12, the PC board assembly 2, the upper trim 11 and the hook shaft 7 in sequence and then is fixed by a bolt 39.

The light adjusting film 15 is a light adjusting film produced by national ampere-qi latitude photoelectric new material limited company, the light adjusting film type is an energy-saving light adjusting film (wide temperature type), and the color is gray black, so that the light adjusting film has good heat insulation and energy saving effects.

The PCB board 8 is manufactured and processed by Shenzhen Jinli electronics Limited company, the type is a double-sided board, the wiring area is twice as large as that of the single-sided board, the light modulation film 15 is connected with the PCB board 8 through a conducting wire, and the on-off state of the light modulation film 15 is controlled by the light-transmitting switch button 16.

When the automobile sun visor is opened, the power supply is in a closed state, the dimming film area of the automobile sun visor is in an opaque state, the dimming film 15 is in a haze shape, the color is gray black, the shading film is opaque, the automobile sun visor is in an opaque state as a whole, and the automobile sun visor has a good heat insulation effect while blocking light; after an opening button of the light-transmitting switch button 16 is pressed, a power supply is turned on, the light adjusting film 15 is transparent, and the light adjusting film area of the automobile sun visor is in a perspective state, so that the sight of front-row passengers is not obstructed, the driving safety is improved, and the intelligent degree of the automobile sun visor in automobile interior decoration is enhanced; after the off button of the translucent on-off button 16 is pressed, the dimming film region of the car sun visor is restored to the non-see-through state.

About two thirds of the area of the invention is the PC board assembly 2, and the PC board assembly 2 can be controlled to be switched between a perspective state and a non-perspective state under the condition of not shielding light.

The above-mentioned embodiments are intended to illustrate rather than limit the scope of the invention, and it should be understood that various changes and modifications in different forms, which are equivalent to the effect of the present invention, may be made by those skilled in the art after reading the contents of the present disclosure, and these equivalents fall within the scope of the protection defined by the claims of the present application.
